This invention has to do with a plumbing fixture or fitting useful, generally, in pipe lines, and it is a primary' object of the invention to provide a simple, practical and effective fitting which acts asa coupling or connection' between adjoining pipes and`V is operable to' stop or cut off flow through Athe pipes I v t 1s a primary object of my present invention to provide a 'plumbing fitting of the character mentioned which is practical and effective and, at the same time, simple 'and inexpensive of manufacture.

'It is another object ofV my invention to provide a fitting of the character mentioned embodying auxiliary valve means whereby the device acts as a check valve when in operating position in a pipe line.

It is al further object of this invention to 2 provide a itting of the character mentioned involving few simple and inexpensive parts.

The invention is capable of embodiment in numerous forms or detailed arrangements to suitl a large variety of conditions, such as are` encountered in pipe fitting and, to give an understanding of some of the possible variations of the invention, I have set forth in the accompanying drawings several dierent modifications or` embodiments of 3 the invention.

The various objects and features of the invention will be best and more fully understood'from the following detailed description of typical forms and applications of the drawings, the body 10- is designed so that My invention provides primarily a pipe line attachment ory vfitting including, genelally,A av body 10 having an inlet Aopening" 1.1, an outlet opening 12 and a seaty13 opposite the inlet opening, and a threaded coupling member` 14 in the form of-a nipple screwthreaded tothe body to extend into the body through the inlet opening 11 and having a valve vface 15 provided. at'its inner end to cooperate'with the' seat 13:

Referring in particular to Fig. l of the the inlet opening 11 and outlet opening 12 are atright angles to ea yh other. y The openlngs 11 and 12 are pro/vided' with threads, 65 the threads in the opening 11 being adapted to receive the coupling member 14 and the threads in the opening 12 beingadapted to receive a pipe, or the like. In this particular form of the invention, the body isyprovided with a detachable seat member 17 screwthreaded into an opening 18 in the body opposite the' opening 11 to form a wall opposite the opening 11. The seat member 17 Y is providedat'its inner end with a cylindri- 75 cal socket portion 21 at the inner end of which is a beveled seat 13. In the particular construction shown inthe drawings, the outer end` of the seat member 17 is -provided with a socket 22 polygonal in cross sectional configuration to receive a suitable wrench, or the like. The seat member is Aconcealed by a plug 17 a arranged in the outer part of the opening 18. In practice, a washer 'is preferably inserted between the head 19 of the plug and shoulder 20, making 4a fluid tight connection between the plug andmain lpart of the body.

of the body whereby packing 27 can be compressed to prevent leakage of fluid between the coupling 14 and the body. In this form of the mvcntion, the outer'end of the coupling member` 14 is adapted to make asliding connection with a pipe 30 and, for this purpose, has the opening 31 in its outer end finished to slidably receive the'end ortion of the ipe. A packingnut 32 is pre erably screwt readed onto the outer end portion of the couplin 14 so that it isoperable to compress packmg 32 around the pipe 30 at the outer end of the coupling to prevent leakage of fluid between the coupling and pipe. With the arrangement just described, the coupling 14 can be actuated to move the face 15 into and out of cooperative engagement with the seat 13, thus opening and closing the inner end of the coupling member, at

the same time maintaining connection with' the pipe 30. When the coupling-14 is in open position, that is, when it is backed away from the seat` 13 and cylindrical part 21, fluid can pass through the cou ling member and thebody between the p1pe 30 and the pipe arranged in the opening 12. It is to be understood, of course, that the ow may be in either direction through the device.

In accordance with my invention, I may provide an auxiliary valve 35 in the form of a check valve in the body 10, operable to check flow of fluid through the body in one direction. In the particular arrangement shown in the drawings, the check valve 35 is mounted in the body on a pivot pin 36 to cooperate with a seat 37 formed in the body at the inner end of the opening 11.` When the coupling 14 is backed away from the sea't 13 until it 1s moved outwardly past the seat 37', the valve 35 is free to act as a check valve to prevent passage of iuid outwardly through the opening 11. It will be obvious that the valve35 is automatically lifted out of operating position as the coupling 14 is moved inwardly through the body to the closed position.

In Fig. 2 of the drawings, I illustrate a more simple form of the invention in which the body 10a resembles, more or less. an ordinary L or elbow fittinghaving openings lla and 12a arranged at right angles to each other. The interior walls of the body 10a opposite the openings llarI and 12a. are provide with seats 13a to'receive faces a provided on the. inner ends of coupling members 14a screwthreaded in the openings 11a and`12a. In this construction, cylindrical socket parts 21a may be provided in the body to receive finished parts a at the inner ends of the coupling members 14a. The coupling members 14a in this case may keither one of the coupling member 14a may be arranged in closed position, while the other coupling member is open, or both couy pling members may be in open position. ln

the drawin I have shown one coupling member in c osed position and the other coupling member in open position.

In Fig. 3 of the drawings, I have shown another y embodiment of the invention, in which case the body 10b is made more or less in the form of a cross-over fitting having openings 11b at its ends and an open o enin 12b intermediate its end s. The bo y 10 in this case is semi-circular in its general conguration. The openings 11b at the ends of the body extend radially or in diametricall opposite directions so that they are co-axia while the opening 12b, as shown in the drawings, is in the middle portion of the body extending radially with reference tothe axis of the body. With this arrangement, it will be obvious that the body presents a wall ope posite each opening. The walls of the body opposite the openings may be provided with seats 13b and, if desired, with sockets 2lb, as described in the case of the other forms of the invention.

Coupling members 14?), similar to those above described, may be operated in the openings, as Will be obvious from the drawings.

In Fig. 4 of the drawings, I illustrate another embodiment of the invention in which the body is an elongate member more or less in the nature of a header. The body has a plurality of lateral openings and the walls of the body opposite the openings are provided with seats 130 to cooperate with faces 15e on the ends of coupling members 140 that may be arranged in the openings.

The form of the invention illustrated in Fig. 5 of the drawings is similar, generally, to that shown in Fig. 2 of the drawin s, except that the two openings in the bo y 10d are arranged differently. In this particular case, the openings are parallel but offset so that the body 10d presents interior walls opposite the openings suitable for the provision lof the necessary seats 13d.

From the foregoing description of the various forms of the invention, it will be obvious that the openings in the body may be arranged in any desired relation, and it will be apparent how the device can be easily and cheaply manufactured. In operation, the device may be usedas an ordinary pipe fitting or coupling to join two adjacent pipes and, whenever necessary, it can be manipulated to shut oil' the flow through the pipes. In general, the device may be used in the place of a shut-oii valve, and is of practical merit in that it accomplishes the general function of a shut-0E valve Without involving the structural complications of such a device and without occupying the space necessary for an ordinary shut-oli:` valve.

Having described only a typical preferred form of my invention, I do not wish to limit myself tothe specific details set forth, but wlsh to reserve to myself any changes or variations that may appear to those skilled in the art or fall within the scope ofthe followin claims.
